IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 213,627, dated March25, 1879 application filed February 17, 1879.

To all whom it may concern Be it known that I, PATRICK V. COOGAN, of thecity, county, and State of New York, have invented a new and usefulImprovement in Lanterns for Use in Millstone-Dressing, of which thefollowing is a specification:

Figure l is a front elevation of the lantern. Fig. 2 is a sectionalelevation through line as a. Fig. 3 is an elevation of a reflector.

Similar letters of reference indicate corresponding parts.'

The object of this invention is to provide a lantern for use inmillstone-dressing that shall throw a clear light upon the land orfurrow of the stone, and that shall not only convey away all the smokegiven off by the lamp, but also the fine dust arising from the dressing0f the stone.

The invention consists of a conically-shaped lantern-body, A, prolongedupward into achimney, with an elbow or bend, a, in it.

Alamp, B,is placed within the lantern-body through the opening 0, andthe lamp is furnished with an adjustable reflector, D, to reflect itslight forward out of the lantern-body.

The hood E is secured to the lantern-body by being thrust partiallythrough the opening 0, and by the engagement of its ear b in the loop(1. This hood is adjustable at different angles, and has its undersurface polished, to serve as a reflector. Its most effective position,ordinarily, is as shown in the drawing. In this position it does notinterfere with the light reflected from the reflector D, but reflectslight from the flame downward and outward, while, in combination withthe reflector D, it forms a narrow flue, as appears at f, that induces astrong upward current of air.

The burner or wick of the lamp B is placed as near as possible to theouter edge of the opening 0, so that its light may be better thrown uponthe millstone.

When this lantern is used it is found that the hood screens the lightfrom the eyes of the operator; that the draft caused by the burning lampcarries with it all the fine and light stone-dust raised by the strokesof the pick upon the stone, and prevents it from entering the lungs ornostrils of the workman, while the chimney conveys the smoke and finedust away above the head of the workman, and, by means of the elbow orbend in it, directs their current from him.

By the use of this lantern the stone-dresser is enabled, by theclearness of the light, to sit upright at his work, so that the heavierdust and particles of grit made that will not be drawn up by thelantern-chimney cannot reach his mouth or nostrils.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The improved lantern consisting of Iantern-body A,with elbow a, lamp B, reflector D, and hood E, substantially as hereinshown and described.

2. In combination with a conically-shaped lantern-body, the lamp B,reflector D, and hood E, substantially as herein shown and described.

3. The conically-shaped lantern-body A, with elbow a, substantially asand for the purpose described.

4. In the construction of a lantern, the combination of lamp B,reflector D, and hood E, substantially as and for the purpose described.
